Pomaderris paniculosa subsp. paralia

FAMILY: RHAMNACEAE BOTANICAL NAME: Pomaderris paniculosa subsp. paralia N.G.Walsh, Muelleria 7: 276 (1990) COMMON NAME: Shining dogwood COMMONWEALTH STATUS: (EPBC Act) Not Listed TASMANIAN STATUS: (TSP Act) rare

Pomaderris paniculosa subsp. paralia Tasmanian Herbarium specimen.

Description A compact much-branched shrub to 2 m high. Leaves: The leaves are ovate to elliptic, 15–50 mm long and 10–25 mm wide, relatively thick, with entire (rarely irregularly crenate) margins and a round or blunt apex. The lower leaf surface is covered by fine white stellate hairs, overlain (mainly on the veins) with scattered, larger, often rust-coloured stellate hairs, while the upper leaf surface is hairless and shining. Stellate hairs extend to the margins of the upper leaf surface, creating a narrow white border that characterises species in the Pomaderris oraria complex (Curtis & Morris 1975). Flowers: The inflorescence consists of axillary and terminal panicles, with several, more or less globular clusters of flowers, each panicle being considerably longer than the subtending leaves. The flowers are on short stalks, with greenish-brown sepals to 2.5 mm long and a deeply trifid style; there are no petals. Flowering is from October to November. Fruit: The fruit is a dry capsule c. 3 mm long, opening by three valves to release pale-brown flattened seeds (description from Curtis & Morris 1975 and Walsh 1990). Confusing species: Pomaderris oraria subsp. oraria (bassian dogwood) — the upper leaf surface of this closely allied taxon is hispid.

Distribution and Habitat Pomaderris paniculosa subsp. paralia occurs in Western , South Australia and (Walsh 1990). In , the species has been recorded from coastal sites in the northeast, the and King , where it grows in exposed sites along clifflines and within dune scrubs (it also reputedly occurs in inland areas of near Wingaroo).

Key Sites and Populations Key sites include Croppies Point, Cape Portland, , Prime Seal Island, East Sister Island, Outer Sister Island and Erith Island.

Known Reserves Reserved in National Park, Mussleroe Bay Conservation Area, Seal Rocks State Reserve, Sister Conservation Area and Waterhouse Conservation Area.

Ecology and Management Insects are the most likely pollination vector for this species (A. Hingston pers. comm.).

Conservation Status Assessment Pomaderris paniculosa subsp. paralia and Pomaderris oraria subsp. oraria are components of what used to be known in Tasmania as Pomaderris oraria (Curtis & Morris 1975; Walsh 1990). Walsh cited the distribution of the two taxa in Tasmania as follows: Pomaderris oraria subsp. oraria (Badger Head), and Pomaderris paniculosa subsp. paralia (north coast and islands). Pomaderris oraria subsp. oraria has since been confirmed from Flinders Island (Tasmanian Herbarium). The identity of ‘Pomaderris oraria’ records in the northeast and Flinders Island that lack supporting herbarium specimens needs to be resolved before a reassessment of the conservation status of either taxa can be undertaken.
